Agent Infrastructure Platform

Plug production tools into your agents.

BuildE2E is the infrastructure layer for agent products. Integrate Fetch, Code Sandbox, and Browser Sandbox with one SDK and one API key, without building scraper fleets, runtimes, or browser orchestration from scratch.

No credit card required. Get started for free.

Direct integration

Expose core capabilities directly to agent frameworks with minimal setup.

No infra code

We handle scaling, reliability, and isolation so your team focuses on product.

agent-runner.ts

import BuildE2E from '@builde2e/sdk';
import { generateText } from 'ai';
import { openai } from '@ai-sdk/openai';

BuildE2E.setApiKey(process.env.BUILDE2E_API_KEY!);

const { text } = await generateText({
  model: openai('gpt-4.1-mini'),
  tools: {
    fetch: BuildE2E.tools.aiSdk.fetch,
    executeCode: BuildE2E.tools.aiSdk.executeCode
  },
  prompt: 'Fetch the top AI agent frameworks page, then rank by GitHub stars.'
});

console.log(text);
// -> ranked frameworks with citations

Products

Production APIs for scraping and automation.

Scraping Product

Scraper API

The fastest and most stealth scraper pipeline for dynamic sites, anti-bot pages, and LLM-ready extraction.

  • Speed + stealth fallback
  • Markdown/HTML output
  • Public live tester available
Explore Scraper API

Platform

Four core tools. One infrastructure layer.

Fetch (Any Web Content)

Fetch clean content from any URL, including dynamic JavaScript-heavy pages.

  • Markdown or HTML output
  • Consistent extraction at scale

Code Sandbox

Run generated Python and JavaScript safely in isolated runtimes before agents take action.

  • Isolated execution
  • Deterministic runtime behavior

Browser Sandbox

Use managed browser sessions for computer-use agents and real web interactions.

  • Session APIs + live control
  • Production-grade browser orchestration

LLM Router

Coming Soon

Route requests to the right model/provider with centralized control for agent workloads.

  • Model routing policies
  • Cost and performance optimization

Workflow

Integrate once. Compose workflows. Ship faster.

  1. 01

    Integrate

    Connect once with one SDK and one API key, then expose tools directly to your agents.

  2. 02

    Compose

    Combine Fetch, Code Sandbox, and Browser Sandbox to extract, validate, and act in one flow.

  3. 03

    Act

    Use Browser Sandbox when agents need to navigate and act on live websites.

Outcomes

Infrastructure handled. Agent product velocity unlocked.

4

Core tools behind one API

1 key
